To @ZZ whom t may concern.-

Beit known that I, HENRY J. OAsE,a citizen of the United States,residing at Auburn, in the county of Cayuga and State of New York,

have invented a new and useful Improvement in Grain-Bindersjof which thefollowing is a specification.

This invention relates to grain-binders of well-known construction,which contain 'a 1o compressor serving asy an abutment against which thegavei of grain is pressed, a needle whereby the cord or twine is passedaround the gavel, and a knotter mechanism.

The objects of my invention are toimprove 5 controlled and to improvethe knotter mechanism.

In the accompanying drawings, consisting of four sheets, Figure 1` is anend elevation of the binder-deck of a grain-harvester provided with myimprovements. Fig. 2 is a Vertical transverse section of the knottermechanism, taken in line 2 2, Fig. 9. Fig. 3 is a vertical section inline 3 3, Fig. 2. Fig. 4 is a fragmentary top plan view of thebinder-deck and the binder mechanism. Fig. 5 is a horizontal section ofthe knotter mechanism, taken in line 5 5, Fig. 9.

Fig. 7 is a horizontal section of the bindermechanism, taken through the bearingof the needle-shaft. Fig. 8 is afragmentary horizontal section in line 8 8, Fig. 9. Fig. 9 is a verticalsection taken in line 9 9, Figs. 4 and 7, and showing the position of 1ihe parts preparatory to binding a gavel. Fig. 10 is a similar viewshowing the position of parts while tying a band around the gavel. Fig.ll is a fragmentary vertical section in line 1l ll, Fig. S5-showing theparts in the same relative position as in Fig. 9. Fig. l2 is a similarView showing the parts in the same relative position as in Fig. lO. Fig.13 is a fragmentary side elevation of the needle and connecting partsviewed from the side opposite to that shown in Fig. ll.

Like letters of reference refer to like parts in the several figures.

The frame of the binder mechanism conthe mechanism by which thecompressor isv sists,essentially,of two longitudinal bars A', arrangedunderneath the binder deck B, front, intermediate, and rear cross-piecesa a/ standard O, secured to the intermediate and rear cross-pieces'andoverhanging the binderdeck.

. D, Figs. l, 7, 9, and 10, represents the constantly-rotating main orpacker shaft, journaled in bearings on the cross-pieces, and E E are thepackers, which are operated by the cranks d d on the main shaft. Frepresents the binder-needle, secured to the front end of thevneedlerock-shaft f, which is jonrnaled in bearings in the standard below thebinderdeck. G, Fig. 7, represents the intermittently-rotatingcounter-shaft, journaled in bearings in the intermediate and rearcrosspieces and provided atits rear end with a crank g. This latter isconnected by a connecting-rod g with a crank g2, which is arranged onthe rear endof the needle-shaft and'which is of greater length than thecrank g of the counter-shaft. The front end of the countershaft isprovided with a gear-wheel g3, which meshes with a gear-pinion g4,mounted loosely on the main shaft. The gear-pinion is coupled with anduncou pled from the main shaft by a clutch-arm t, pivoted eccentricallyon the gear-pinion and provided with a clutch ringer or shoulder h,which can be shifted into or out of the path of the driving-dogs h2,mount-ed on the main shaft. f The clutch-arm is turned in a directionfor bringing its clutchshoulderinto the path of the driving-dogs by aspring h3, and the clutch-arm is turned in the opposite direction formoving its clutchshoulder out of the path of the driving-dogs by theinner or rear arm z' of a trip-lever I. The front arm '1I' of this leverprojects normally above the binder-deck and is connected with the reararm i by a hub i2, which is journaled on the outer or front longitudinalbar A of the mainframe. The trip-lever is yield` ingly held with itsinner arm in engagement with the clutch-arm and with its outer armprojecting above the deck by a spring v113, bearing with one end againsta perforated ear t4 on the hub of the trip-lever and with its oppositeend against a screw-nut on an adjusta2, connecting the longitudinalbars, and a I IOO ing-rod r", the latter' passing through said ear andpivotally connecting with the standard or other part of the stationaryframe. The expansion of the spring @"3 is limited by means of a link i6,which is provided at one end with a pin engaging with a slot i in theouter arm of the trip-lever, and which is pivoted at its other end to acollar 8, secured to the needleshaft adjacent to the rear side of thehub of the needle, as shown in Figs. 7, i), and lO. lVhen a sufficientamount of grain has accumulated on the deck to form a bundle, the outerarm of the trip-lever is depressed by the grain and its inner arm isdisengaged from the clutch-arm, as represented in Fig. 9, therebycoupling the counter-shaft with the main shaft and rocking the needlefor passing the cord around the bundle in a wellknown manner. Theslotted connection between the link t6 and the front arm of thetrip-lever permits the latter to be turned independently of the needlefor coupling the clutch. \Vhen the bundle has been removed from thedeck, the spring i shifts the triplever for lowering its inner arm intothe path of the clutch-arm and uncoupling the clutch, as represented inFig. 9. All of these parts are of well-known construction.

My improved mechanism for controlling the compressor is constructed asfollows:

J represents the arm of the gavel compressor, which projects normallyabove the binder-deck and which is pi voted at its lower end to thecompressor-bar j near the outer end thereof. The arm J is provided onthe outer side of its pivot with a heel or projection, which is arrangedover the outer end portion of the barj. A spring j is interposed betweenthe end portion of the barj` and the heel of the arm J. This springholds the arm in its normal position, but allows it to yield outwardlyto a limited extent. rlhe inner or rear end of the compressor-bar ispivoted to a crank or lug jl, which is arranged on the hub of the needleon the side opposite to that on which the point of the needle isarranged.

js is a lifting lug or toe arranged on the compressor-bar on the innerside of its pivot and projecting underneath lthe hub of the binderneedle. During the downward or backward movement of the needle thelifting-toe engages with the hub of the needle, whereby the compressoris compelled to move upwardly with the compressor-lugj2 and carry itsarm above the binder-deck.

K represents an upright supporting-arm whereby the compressor is held inits elevated position during the operation of tying the cord around thegavel, and which is pivoted at its lower end to the intermediatecrosspiece of the main frame by a transverse pin or bolt le, so that thearm can swing backwardly and forwardly in the same plane as thecompressor. The supporting-arm is provided with a longitudinal slot 7d,the upper end of which extends forwardly at an angle to the lowerportion of the slot and forms an upwardlyfacing socket or shoulder 7.52on said'arm.

7c3 is a roller or projection arranged on the front portion of thecompressor-bar and engaging with the slot of the supporting-arm. Thecompressor is held in its elevated position by engaging the shoulder ofthe supportin g-ar m with the projection of the compressorbar, thesupporting-arm being yieldingly pressed inwardly for this purpose by aspring 7a4, surrounding the pivot of the supportingarm, as shown inFigs. 7, 8, 9, and 10. Upon moving the supporting-arm forwardly againstthe pressure of the spring 7a4 suliciently to disengage the shoulderthereof from the projection of the compressor-bar the compressor ispermitted to drop, so that its arm clears the binderdeck, during whichmovement the projection of the compressor-bar drops through the slot ofthe supporting-arm to the lower end thereof, as shown in Fig. l0.

L represents a releasing-bar whereby the supporting-arm is released fromthe compressor, and which is pivoted at its front end to one side of thesupporting-arm. The rear end of the releasing-bar is preferably curvedupwardly and held yieldingly against the under side of the hub of theneedle by a spring l, which surrounds the pivot of the releasingbar. Therear end of the releasing-bar is held against lateral displacement by anupwardly-projecting guide-lug Z', arranged on the hub 112 of thetrip-lever and engaging with a longitudinal slot Z2 in thereleasing-bar.

m is a hook-shaped nose or shoulder arranged on the compressor-crankj2and adapted to engage with a similar nose or shoulder a on the upperside of the adjacent rear portion of the releasing-bar. During theforward movement of the needle the compressor while in an elevatedposition is moved backwardly by the compressor-crank, which latter movesin a direction opposite to that of the point of the needle, whereby thegavel is compressed between the needle and the compressor-armpreparatory to tying the cord around the gavel. During the last portionof the upward movement of the needle its compressor-crank deilects thereleasing-bar downwardly, and when the shoulder of the compressor-crankhas passed in rear of the shoulder of the releasing-bar the latter islifted by the spring l, so that its shoulder or nose stands in front ofthe shoulder or nose of the compressor-crank. During the first portionof the subsequent backward movement of the needle the nose of itscompressorcrank while moving forwardly engages with the nose of thereleasing-bar, as shown in Figs. l() and 12. During the next portion ofthe backward movement of the needle and the forward movement of itscompressorcrank the latter moves the releasing-bar forward, togetherwith the supporting-arm, whereby the shoulder 7a2 of the supporting- IOOIOS

. pressing the next gavel.

arln is disengaged from the projection 7c3 of the compressor-bar,therebycausin g the latter to drop quickly with its arm below the binder-v deckand permitting the bundle to be discharged from the deck. During thecontinued backward movement of the needle after'the compressor has beendepressed the compressor-crank moves upwardly and the rear end of thereleasing-bar engages with the under side of the hub of the binderneedleand is prevented from following the upward movement of the nose of thecompressor-crank, whereby this nose is disengaged from the nose of thereleasing-bar. After the releasing-bar is disengaged from thecompressor-crank the toe js of the coinpressor-bar engages with the hubof the needle and during the last portion of the backward movement ofthe latter the compressor is raised into its operative position by thecompressor-crank. When the compressor has reached its highest position,the supporting-arm is moved backwardly by the spring 704 and itsshoulder k2 is carried underneath the projection 7c3 of thecompressor-bar, as represented in Fig. 9, thereby holding the same` inan elevated position during the forward movementof the needle while com-If desired, the lifting of the releasing-bar for carrying its shoulderin front of the shoulder of the compressorcrank may be effected byinclining the front side of the guide-lug Z', as shown at o, Figs. 10,11, and l2. This incline is engaged by the front end of the slot Z2 inthe releasingbar during the last portion of. the backward. movement ofthe releasing-bar and its shoulder is carried up in front of theshoulder of the compressor-crank, so that during the subsequent forwardmovement of the latter the shoulder of the releasing-bar will be engagedby the shoulder of the compressor-crank for disengaging thesupporting-arm from the compressor.

My improved knotter mechanism is constructed as follows: v

P represents the knottershaft, which is journaled in the upper portionof the standard C; p, the knetter-frame, hung on said shaft; p', thebreastplate, secured to the lower portion of the knotter-frame; Q, therotary tying-bill, j ournaled on the knotter-frame and provided with abevel gear-pinion q; R, the

'rock-lever, pivoted on the knotter-frame and provided with a cord-guider in rear of the tying-bill and a cord-cutter r' in front of said bill;S, the knotter wheel, secured to the knotter-shaft on the front side ofthe knotterframe and provided with a cam-groove s, which operates thecord guide and cutter, and with a gear-segment s,f which intermittentlyoperates the tying-bill, and s2 the bundle discharging or ejector arm,which is secured to the knetter-Wheel. This portion of the knottermechanism is'of well-known construction. T represents the cord clampingdisk,

mounted horizontally or nearly so on a pivot on the knetter-frame infront of the tyingbill and cutter and provided in its edge withcord-receiving notches, each of which has an inclined or curvedadvancing sidet and an abrupt trailing side t. 2 is a cord-clamping armpivoted at its front end to the knetterframe and provided with a groovewhich receives the edge of the clamping-disk and forms two jaws t3 t4,arranged above and below the disk. The clamping-arm is yieldinglypressed against the clam ping-disk by a spring t5. After the cord hasbeen laid by the needle across the cord-guide and tying-bill and intoone of the notches of the disk the latter is turned forwardly throughthe clamping-arm, whereby the cord is clamped between the bottom of thenotch in the disk and the jaws of the clamping-arm. During thesubsequent turning of the tyin g-bill for forming the knot in the cordthe latter is strained, thereby producinga pull on the disk which causesthe latter-to be turned forward slightly and to supply the necessarycord yfor forming the knot. By inclining the advancing sides of thenotches in the clamping-disk the cord upon being pulled by thetying-bill is wedged between the inclined side of the notch and theclamping-jaws, thereby increasing the grip of the clamping devices uponthe cord in proportion to the pull on the cord and preventing theclamping-disk from being turned by the pull of the cord to such anextent as to displace the clamping-disk and prevent the cord from beinglaid into the next-following notch by the needle. In order to preventthe cord from being pulled out of the clampingjaws by the tying-bill orthe cutter, the upper clamping-jaw is provided with a forwardlyfacinghook t6, which intercepts the cord as it is carried rearwardly bytheclamping-disk and tyin g-bill. U represents a rock-lever whereby theclamping-disk is rotated intermittently, and which :is pivotedv to theknotter-frame, so as to swing transversely. This construction of clampcauses the clamping-disk to be wedged in the clamping-arm sufficientlytight to render the usual detent-pawl for holding the disk againstbackward movement unnecessary. The lower arm of the rock-lever isprovided with a pawl u, which engagesrwith a ratchetwheel u on the underside of the clampingdisk. This pawl is pivoted on a holder u2, arrangedin a socket in the lower arm of the lever, and is yieldingly held inengagement with the ratchet-wheel by a spring M3, interposed between theholder and the pawl. The pawl is adj usted in the lever by a screw n4,arranged in the lever and bearing against the holder, and the latter isheld in its adjusted position by a set-screw n.5. The rock-lever U isrocked by a grooved cam fu, which is mounted on the knotter-shaft on theside of 'the knotter-frame opposite to that on which the knetter-wheelis arranged and which engages with the upper arm of the rock-lever forop.-

erating the clamping-disk. The clampingcam is provided withadischarge-arm o. By arranging the wheel S and cam 1J for operating theknotting and clamping mechanism on opposite sides of the knotter-framethe strain upon the parts is better distributed and the separate partscan be made of simpler construction. In the operation of the knottermechanism the cord is carried by the needle around the gavel and graspedby the clamp. The tying-bill then rotates and forms the loop in thecord, and at the end of this movement the cutter severs the cord betweenthe tyingbill and the clamp, and the cord-guide strips the loop from thetying-bill and completes the knot in the cord. The bundle is thendischarged from the binder-deck by the discharge-arms.

My improved mechanism for driving the shafts of the needle and knotter'mechanisms is constructed as follows: The knotter-shaft is rotated fromthe counter-shaft G once during the operation of tying each bundle. Themotion is transmitted from the counter-shaft to the knotter-shaft by aforked connectingrod XV, which is pivoted at its rear end to the crank gof the counter-shaft and at its front end to a crank w on the end of theknottershaft. The intermediate portion of the connecting-rod ispivotally connected with the standard C by a guide-crank w', the latterand the cranks of the counter and knotter shafts being of the samelength. During the operation of tying a bundle the counter-shaft makesone rotation in the direction of the arrow, Fig. 1, and then stops, andthe knottershaft is also rotated once and in the same direction as thecounter-shaft by the connecting-rod W, which latter is compelled to movein a circle and make a complete turn by the guide-crank 1r. At thebeginning of the binding operation the several cranks stand in aforwardly-depending position, as shown in Fig. l. As the counter-shaftrotates the leverage of the counter-shaft crank increases as the crankpasses the dead-center in rear of the counter-shaft, at which time theneedle has reached the end of its forward movement and the gavel hasbeen compressed to the fullest extent. During the compressing operationof the needle and compressor the knotter mechanism is at rest; but whenthe counter-shaft crank has passed the dead-center the knotter mechanismperforms its operation and then the discharge-arms remove the bundlefrom the binder-deck. Vhile the bundle is being removed from the deck,the cranks of the counter and knotter shafts are moved forwardly throughthe lower portion of the circle, in which position the leverage of thesecranks is most efective in relation to the knotter mechanism. By thisarrangelnent of the driving mechanism of the needle and the knottermechanism the strain upon the parts is properly distributed, therebyenabling the same to be made lighter.

By transmitting the motion from the counter-shaft to the knotter-shaftby means of a connecting-rod the construction of the driving mechanismis simplified and its cost is reduced and the parts are enabled to beassembled without requiring particular attention to keep the severalparts in time with each other, which is not the case where the motion istransmitted by a chain belt and sprocketwheels from the counter-shaft tothe knottershaft.
